ok i'm trying to learn zshell and when i try to assemble this sample
program from a tutorial:

 #include "ti-85.h"

 .org 0
 .db "My first program!",0

   ROM_CALL(CLEARLCD)
   ld hl,0
   ld ($800C),hl
   ld hl,Text
   ld de,(PROGRAM_ADDR)
   add hl,de
   ROM_CALL(D_ZT_STR)
WaitKey:
   call GET_KEY
   cp K_EXIT
   jr nz,WaitKey
   ret

Text:
 .db "Hello World!",0

 .end

it says this:

TASM Z80 Assembler.       Version 3.0.1  June, 1994.
